DIY Gas Strut Replacement: An Overview

Replacing gas struts is a common DIY task applicable to various items, from car boots to cabinet doors. This guide provides a step-by-step approach to measuring, selecting, and installing replacement gas struts, ensuring a safe and effective repair. Before you begin, make sure you have a replacement gas strut from a trusted supplier like Aritech Gas Springs.

Why Replace Gas Struts Yourself?

Replacing gas struts yourself can save money compared to hiring a professional. It’s also a relatively simple task that most DIY enthusiasts can handle with basic tools. Ensure you handle old struts carefully. If you’d like to calculate force, visit our gas strut force calculator.

How Do I Know My Gas Strut Needs Replacing?

Gas struts typically fail gradually, exhibiting symptoms like slow operation, inability to hold weight, or complete failure to extend or compress. If your car boot or cabinet door no longer stays open, the gas strut likely needs replacement.

What Tools Do I Need for Gas Strut Replacement?

The tools required for gas strut replacement are typically minimal. You will generally need a flathead screwdriver, a new gas strut and potentially a friend to apply pressure.

  • Flathead screwdriver
  • New gas strut
  • Safety Glasses
  • Gloves
  • Assistant (optional, for holding heavy lids)

How to Measure a Gas Strut for Replacement

Proper measurement is crucial for selecting the correct replacement gas strut. Measure is millimetres, or inches if you’re in the USA

Extended Length

Measure the distance between the mounting points when the strut is fully extended. This is the most important measurement.

Compressed Length (Stroke)

Measure the distance between the mounting points when the strut is fully compressed. This helps define the strut’s range of motion.

Force Rating (Newtons)

The force rating, measured in Newtons (N), indicates the strut’s lifting capacity. This is usually printed on the strut body. If illegible, use our gas spring force calculator to estimate.

End Fittings

Identify the type of end fittings (e.g., eyelets, ball joints) to ensure compatibility with your application. See our gas strut end fittings guide for detailed illustrations.

Step 1: Gather Your Tools and Materials

Ensure you have all the necessary tools and your replacement gas strut ready before starting.

Step 2: Prepare the Work Area

Clear the area around the strut to allow easy access and movement. For car boots or engine hatches, ensure the area is well-lit and stable.

Step 3: Secure the Lid or Hatch

Before removing the old strut, secure the lid or hatch with a prop or have an assistant hold it. This prevents accidental closure and potential injury.

Step 4: Remove the Old Gas Strut

Use a flathead screwdriver to gently pry off the retaining clips or spring clips that hold the strut in place. Be careful not to damage the mounting points. On automotive applications, it might be easier to watch a YouTube video.

Step 5: Install the New Gas Strut

Align the new gas strut with the mounting points and snap it into place. Ensure the retaining clips are securely fastened. Some struts may require a bit of force to compress and align. For caravan and marine, you should consider a high grade of stainless steel and read our article on marine gas struts

Step 6: Test the Operation

Carefully remove the prop or have your assistant release the lid or hatch. Test the operation of the new strut to ensure it smoothly opens and closes. It is important to know the gas spring newton force. If it’s not behaving as it should, perhaps your gas strut is stuck closed?

Safety Tips for Gas Strut Replacement

These safety tips are important to adhere to:

  • Wear safety glasses to protect your eyes from debris or accidental spring releases.
  • Wear gloves to improve grip and protect your hands.
  • Never attempt to disassemble a gas strut, as it contains high-pressure gas.
  • Always secure the lid or hatch before removing the strut to prevent accidents.

Common Mistakes to Avoid

Avoiding mistakes is key for a smooth installation:

  • Ordering the Wrong Size: Double-check your measurements before ordering a replacement.
  • Forcing the Strut: If the strut doesn’t easily snap into place, recheck the alignment and mounting points.
  • Ignoring End Fittings: Ensure the end fittings match your application to avoid compatibility issues.

Where Can I Buy a Replacement Gas Strut?

Replacement gas struts are available from various sources, including automotive parts stores, DIY shops, and online retailers. Ensure you purchase from a reputable supplier like Aritech Gas Springs to ensure quality and reliability.

The Automotive Angle

Gas struts are used in many automotive applicaitons. This includes boots, engine bays, and more. If you’re buying an off-brand gas strut, always compare OEM vs aftermarket gas struts to make sure you are getting a great one.
